We cannot guarantee in all cases the absolute correctness of the forms of the poems given, though much pains have been taken to ensure accuracy; but authors themselves make changes in their productions at different times in different editions. Nor have we always been able to trace the poem to its source. Slips and errors of various kinds can hardly be avoided in such matters. Even so competent an editor as John G. Whittier, in his "Songs of Three Centuries," ascribes "Love divine, all love excelling" to that bitter Calvinist, Augustus M. Toplady, giving it as the sole specimen of his verse; when it was really written by the ardent Arminian, Charles Wesley, with whom Toplady was on anything but friendly terms. If Whittier could make a blunder of this magnitude we may be pardoned if possibly a keen-eyed critic spies something in our book almost as grossly incorrect. In some cases we have been obliged to change the titles of poems so as to avoid reduplication in our index, or to adapt them the better to the small extract taken from the much longer form in the original. In a few cases we have made (indicated) alterations in poems to fit them more fully to the purpose of the book. The volume will be found not only a readable one, we think, but also an uncommonly useful one for presentation by those who would do good and give gratification to their serious-minded friends with a taste for religious poetry and a love for wandering in the "holy land of song." He who would put before another the essential elements of religion would do better to give him such a book as this than a treatise on theology. He who would himself get a clear idea of what the religious life really is will do better to pore over these pages than to dip into some philosophical discussion. Here the best life is expressed rather than analyzed, exhibited rather than explained. Mrs. Browning has well said, "Plant a poet's word deep enough in any man's breast, looking presently for offshoots, and you have done more for the man than if you dressed him in a broadcloth coat and warmed his Sunday pottage at your fire." We who, by preparing or circulating such volumes, aid the poets in finding a larger circle to whom to give their message, may claim a part of the blessing which comes to those who in any way aid humanity. George Herbert has said, "A verse may find him who a sermon flies, And turn delight into a sacrifice." He himself most excellently illustrated the sentiment by bequeathing to the world many beautiful verses that are sermons of the most picturesque sort.
